Application June 22, 1945, Serial No. 601,016

1 Claim. 1

This invention relates to internal combustion engines and has for itsobject to provide means for preventing vapor condensation from returninginto the oil pump of the engine.

Another object of this invention is to provide an arcuate cap for therocker arm of a valve in head engine having a gutter into which thecondensation of raising vapor will flow and means for directing the sameoutwardly of and away from the cylinder block.

Other features and advantages will become more readily apparent from thefollowing description and the accompanying illustrative drawings inwhich:

Figure 1 is a transverse sectional view of the top of an internalcombustion motor,

Figure 2 is a reduced perspective view of my device, and

Figure 3 is a similar view of a modification.

In the accompanying drawings as above enumerated and in the followingspecification, like characters of reference indicate like partsthroughout and in which l0, indicates my invention which consists of acap II, to fit over the rocker arm l2, of an internal combustion motorand against the upper wall l3, of the casing M, for the top of saidmotor. The member ll, consists of an elongated arcuate plate terminatingat its lower edges in a surrounding gutter l5, inclining to an outletI6, to which is attached a tube l'l, projecting through an aperture inthe wall of the member I4. An opening [8, is provided in the center ofthe device through which the bolt l9, projecting from the rocker armsupport 20, extends. On this bolt I provide a spring 2 I, and a washerplate 22, above the spring which bears against the top wall 23, of themember II, and holds it securely against the wall I3. From the tube ll,extends a flexible tube 24, for carrying off the drainage fromgutter 15.

In internal combustion motors vapor arises from the oil sump and otherparts of the motor and passes through the apertures of the rods 25, 26,etc., and usually collects upon the surface of the wall l3, where itcondenses and a considerable part of which falls on and follows the rods25, 26, etc., and returns to and mixes with the oil in the sump, whichof course is injurious to the motor. Therefore, I have provided theabove described means of collecting this condensation and carrying it01f from the motor.

In Figure 3 I show a modification of the invention to be used inconnection with motors having a flat top motor head casing. In this formof the invention the member 21, is formed in one continuous piece, notbeing divided centrally and is provided on its ends with recesses 28 and29 to receive projections usually found in the top of the casing head atthe opposing ends thereof. Otherwise, the device is arranged as thepreferred form.

It is thought that persons skilled in the art to which the inventionrelates will be able to obtain a clear understanding of the inventionafter considering the description in connection with the drawings.Therefore, a more length description is regarded as unnecessary.

Minor changes in shape, size and rearrangement of details and parts suchas come within the purview of the invention claimed may be resorted to,in actual practice, if desired.

Having now described my invention that which I claim as new and desireto procure by Letters Patent is:

In combination with an internal combustion engine having overhead valvesand rocker arms with tappet rods for actuating the same, and a removableinverted U-shaped casing therefor supported upon the head of saidengine, of an inverted U-shape oil vapor collecting cap supported withinsaid casing being of a similar shape thereto and disposed in contactwith the inner wall thereof, said oil vapor collecting cap being formedwith an inwardly disposed inclined trough bent to extend upwardly aboutthe peripheral adge of said cap, and a discharge tube connected with thelowest portion of said trough adapted to carry off the used oil from thecondensed oil vapor which collects in said trough for preventing thesame from returning to the oil in the engine crank case.
